The Effect of Pollutants Dissolved Oxygen and Temperature Change (Case Study:Ghezel-Ozen River)
Rivers can absorb certain amounts of contamination relying on different factors such as: river discharge, the primary conditions of the river, the river depth, discharge and the river viscosity of the offloaded wastes in the river. From parameters of water quality point of view, it is recom-mended to determine some parts of the river which are lower than the standard level in order to find out ...
متن کاملModeling chlorophyll-a and dissolved oxygen concentration in tropical floodplain lakes (Paraná River, Brazil).
The need for prediction is widely recognized in limnology. In this study, data from 25 lakes of the Upper Paraná River floodplain were used to build models to predict chlorophyll-a and dissolved oxygen concentrations. Akaike's information criterion (AIC) was used as a criterion for model selection. Models were validated with independent data obtained in the same lakes in 2001. Predictor variabl...
متن کاملmeasurement and simulation of dissolved oxygen in zayande rood river
background: zayandeh-rood river is the only perennial river in the central basin of iran that has fresh water. water from this source is used for drinking, industrial and agricultural purposes. drinking water is extracted from upstream portion (upstream of chamaseman dam) of zayandeh-rood river and therefore its quality is very important. due to growth of population, industry and other factors,...
متن کاملNumerical modelling of dissolved-oxygen in a cold- region river
Dissolved oxygen (DO) content is a critical measure of the ability of water bodies to support healthy aquatic ecosystems. To better understand DO behaviour in large cold-region rivers, a onedimensional water quality model is setup for a ~200 km reach of the lower Athabasca River below Fort McMurray, Alberta using the Mike-11 modelling system. A river-ice model is applied to reproduce ice condit...
متن کاملMeasuring Dissolved Oxygen Concentration in Aquaculture
(DO) is considered the most important water quality variable in fish culture. In the broadest sense, however, dissolved oxygen concentration is no more important than other environmental variables because any factor that is outside the range tolerated by fish can cause stress or death. What makes dissolved oxygen concentration so important in intensive fish culture is the speed with which it ca...
